S ite Characteristics  S outhwestern portion in flood zone AE  Map reflects FEMA published flood zone impacts to site  Areas shaded “ subj ect to inundation by the 100-year flood” as defined by FEMA  Zone AE per FEMA – Base Flood elevation (water surface elevation) determined to be 4924

Proj ect Details  Character Management Design Requirements:  30’ wide open space buffer around perimeter  NV6.1a  15,000 sqft perimeter lots  NV6.1a  Perimeter lots restricted to single story  NV6.1b  No residential fronting on existing streets  NV6.1d  Limit use of block, concrete or similar materials to posts, pillars and similar uses  NV6.1g  S treet lighting limited  NV6.1h

Proj ect Details  Common Open S pace Tentative Map  Development Area – 154.65 acres  Total Lots - 490  Gross Density - 3.17 du/ac  Common Open S pace - 24.25 acres (15.6% )  Open S pace/ Parks – 18.64 ac  Open Channels – 5.61 ac  Four Villages  Villages 1 &3 – 7,000 sqft min  Villages 2 & 4 – 6,000 sqft min

Open S pace Areas  Trail S ystem  Area Plan Goal 10 – S ystem of Trails  New trail established around perimeter will accommodate horse, bike and pedestrian (NVAP 10.2)  Proj ect trails/ sidewalks provide connectivity to existing trails (NVAP 10.6)  All trails/ paths/ sidewalks associated with proj ect will open to public use

Open S pace Areas  24 ± acres of Common Open S pace  Open S pace/ Parks – 18.64 ac  Open Channels – 5.61 ac  Perimeter landscaping per Code  5 parks including one 3.5 acre neighborhood park  All parks open to public  All Open S pace maintained by HOA or LMA

Proj ect Details  Development phased  Backbone roads and drainage channel initial part of development  Proj ect anticipated to generate 4,939 ADT; 478 PM Peak – at BUILD OUT  Received comments from RTC and Washoe County Engineering  Improvements include new Prado Ranch Pkwy and improvements along Lemmon at Nectar S treet  Ties into existing Matterhorn Blvd to perpetuate access  Although not required by the Traffic S tudy or current Development Code, Developer fixing an existing problem by elevating Lemmon Drive 2 feet higher than existing

Proj ect Details  All sewer to Reno S tead Wastewater Treatment Plant  Currently treating 1.7 mgd  COR moving forward with diversion of 0.5 mgd of raw sewage to TMWRF (complete 2018);  Results in treatment of 1.2 mgd  Has capacity for up to 2 mgd  ~110,250 gpd sewer to Reno S tead Wastewater Treatment Plant  Only if/ when City of Reno Will S erve letter is issued  Effluent  ~123.5 AF/ year effluent = 0.9” rise in lake elevation over a full year  Lake typically evaporates ~4’ / year

S tormwater Mitigation  Must mitigate for increased storm runoff due to development and fill in the floodplain  Per Truckee Meadows Regional Design Manual, mitigation may be retention, detention or increased volume within the 100-year water surface area  To mitigate for increased storm runoff peak flows, Volume off-set area to be provided in retention basin on private property along west side of Lemmon Drive  ~300 acres of designated Open S pace available for off-set area  Based on Master Hydrology analysis of existing watershed  ~30,000 cubic yards (19 AF) to be removed from adj acent open space as mitigation for fill within floodplain  Fill required for this proj ect is 1.2M cubic yards; can take Fill from adj acent Open S pace (through City of Reno standard grading permit); enough area to mitigate well above requirements

Regional Benefits  Lemmon Drive elevat ed above flood level from north proj ect boundary to Deodar Way to improve t he existing situation with a safe and viable roadway in the region  Utility infrastructure extended  24 acres of usable open space for community and surrounding residents  Additional 300 acres available as Open S pace to provide additional capacity and mitigate for flooding within S wan Lake  Minimum $5.5M in impact fees
